yet permitting free movement thereof in the reverse direction, and inthis manner the jaws can be accurately adjusted, and firmly.

held in such position for the positive gripping of the work engagedthereby.

Another object of the invention is the provision of a wrench of thischaracter, wherein the locking means is mounted in one of the shanks ina novel manner to assure positive action for the holding of the jaws ofthe wrench in adjusted position and against slipping when grasping thework.

A further object of the invention is the provision of a wrench of thischaracter, which is novel in construction, to render the same strong.positive in action, and accurate in its adjustment.

A still furtherobject of the invention is the provision of a wrench ofthis character, which is extremely simple in construction, thoroughlyreliable and efficient in opera tion, possessing maximum strength anddurability, and also which is inexpensive in manufacture.

With these and other objects in view the invention consists in thefeatures of construction, combination and arrangement of parts as willbe hereinafter fully described, illustrated in the accompanying drawing,and pointed out in the claim hereunto appended.

In the accompanying drawing :Figure 1,

mentary longitudinal sectional elevation.

Fig.4, is a sectional view on the line 44 of Fig. 1.

Similar reference characters indicate corresponding parts throughout theseveral the solid shank 7, for the adjustment of the jaws relative toeach other. I

Formed. on the hollow shank 8, next to the jaw 6, is a guide-way 9,which opens at one end between the jaw 6, and the front edge of thesolid shank 7 while the opposite end of the guide-way 9, is closedwithan enlargement 10, on the shank 8, the opposed sidewalls 11, of theguide-way being formed with slots 12, through which are passed headedfinger engaging pins 13, the same being fixed in a wedge shaped lockingblock or slide 14, arranged for movement in the guide-way 9. to engagebetween the inner end of the jaw 6, and the front edge of the shank 7,telescoped in the hollow shank 8, carrying said jaw 6, for the lockingof the shanks to hold the jaws in adjusted relation to each other.
